573rwhp EFR 8374 FD Rx7

A customer from Aus recently tuned his EFR 8374 setup at higher boost and here are his results. This is 26 psi on E85, with our shorty cast IWG manifold and a T4 1.05 8374 with a Tial 60mm on the turbine housing. This is similar to our entry level kits, but just with an EFR. 3.5" exhaust and large street port. 4 bar map sensor being installed and going to max it out even further soon. Dyno was backed up on another local one within 6rwhp also...

That's great power for only 26 psi, I would have thought you would need 30 psi+ for that turbo...

Wish they had rpm on the bottom. Great power. Do you have the other dyno sheet too, by chance?

I do not have any other dyno charts. I believe that was run to 8200rpm FYI.

They are going to run it again and max it out, and I know the owner wants the RPM on the sheet too...

Not familiar with that dyno

is the magnitude of that correction factor typical for that location?


noticed a few other graphs with correction factors quite larger....guessing the correction factor is typical for those environmental conditions on that dyno

Probably means 1.55% not 1.55

It is almost 30psi based on the dyno sheet and it is a HUB dyno. I have done back to back testing from hub to chassis and the hub will read 10% higher then the chassis dyno.

Any photos of the turbo set up with the EWG on the turbine housing?
